Pace of Technological Innovation using TCT – Evidence in USPTO

Technology Cycle Time (TCT) is an accepted way to evaluate the pace of technological development although it requires some special considerations. A good analogy is how a chainsaw is a good way to cut down a tree, but it also presents many risks, including the inherent risk of felling a large object. Error of judgement, calculation or interpretation could be fatal. Here is some stark evidence that TCT calculations are a reliable indicator of the current technological environment. The speed of technological development is slowing in recent years. Is this only due to the economic situation? Unlikely. TCT in the USPTO shows that the slowing technological development preceded the economic crisis of 2007. Although overall patenting is increasing dramatically, the rate that the technology is replacing itself is actually slowing. Some evidence of this can be seen when you look at the average processor speed in PC’s and notebooks. Although…
